[PATCH] perf test: Add parse-metric memory bandwidth testcase
by John Garry 03 Feb '21

03 Feb '21

Event duration_time in a metric expression requires special handling. Improve test coverage by including a metric whose expression includes duration_time. The actual metric is a copied from the L1D_Cache_Fill_BW metric on my broadwell machine.

[PATCH v2] mtd: spi-nor: check 4-byte address support when parsing 4bait
by Yicong Yang 02 Feb '21

02 Feb '21

The spi-nor core will convert the address mode to 4-btye, without checking whether 4-byte address is supported or not. For example, the 16M s25fs128s1 can work under both 3-byte and 4-byte address and provides a 4bait table. The spi-nor will drive the flash under 4-byte address mode after parsing the 4bait and will cause it unusable on platforms doesn't support 4-byte. Add checking of 4-byte address support when parsing the 4bait table, stop converting the address mode if it's not supported. The issue maybe addressed by moving the address mode set and 4-byte operation check out of paring 4bait table[1], but fix this with this patch to make the flash work properly on some platform first.

This patchset adds dump tm info of nodes, priority and qset in debugfs. Three debugfs files tm_nodes, tm_priority and tm_qset are created in new tm directory, and use cat command to dump their info, for examples: $ cat tm_nodes BASE_ID MAX_NUM PG 0 8 PRI 0 8 QSET 0 8 QUEUE 0 1024 $ cat tm_priority ID MODE DWRR C_IR_B C_IR_U C_IR_S C_BS_B C_BS_S C_FLAG C_RATE(Mbps) P_IR_B P_IR_U P_IR_S P_BS_B P_BS_S P_FLAG P_RATE(Mbps) 0000 dwrr 100 0 0 0 5 20 0 0 150 7 0 5 20 0 0 0001 sp 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0002 sp 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0003 sp 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0004 sp 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0005 sp 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0006 sp 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0007 sp 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 $ cat tm_qset ID MAP_PRI LINK_VLD MODE DWRR 0000 0 1 dwrr 100 0001 0 0 sp 0 0002 0 0 sp 0 0003 0 0 sp 0 0004 0 0 sp 0 0005 0 0 sp 0 0006 0 0 sp 0 change log: V2: add readonly files for dump all nodes, priority and qset info suggested by Jakub Kicinski. previous version: V1: https://patchwork.kernel.org/project/netdevbpf/patch/1610694569-43099-1-git… Guangbin Huang (2): net: hns3: add interfaces to query information of tm priority/qset net: hns3: add debugfs support for tm nodes, priority and qset info drivers/net/ethernet/hisilicon/hns3/hnae3.h | 8 + drivers/net/ethernet/hisilicon/hns3/hns3_debugfs.c | 55 +++++- .../net/ethernet/hisilicon/hns3/hns3pf/hclge_cmd.h | 1 + .../ethernet/hisilicon/hns3/hns3pf/hclge_debugfs.c | 153 +++++++++++++++++ .../ethernet/hisilicon/hns3/hns3pf/hclge_main.c | 1 + .../ethernet/hisilicon/hns3/hns3pf/hclge_main.h | 2 + .../net/ethernet/hisilicon/hns3/hns3pf/hclge_tm.c | 186 +++++++++++++++++++++ .../net/ethernet/hisilicon/hns3/hns3pf/hclge_tm.h | 48 +++++- 8 files changed, 452 insertions(+), 2 deletions(-) -- 2.7.4

[PATCH 0/2] Add check of 4-byte when parsing SFDP 4bait table
by Yicong Yang 01 Feb '21

01 Feb '21

Add check of 4-byte address mode support when parsing SFDP 4bait. Some flash will provide a 4bait table and the spi-nor core will convert the address mode to 4-byte without checking whether it's actually supported or not by the controller. For example, the 16M s25fs128s1 provides the 4bait and will be convert to 4-byte address mode, which makes it unusable on hisi-sfc-v3xx on hip08 platform. Add the check before convert the address mode when parsing the 4bait will solve this issue.

[PATCH v2] iommu: Check dev->iommu in iommu_dev_xxx functions
by Shameer Kolothum 01 Feb '21

01 Feb '21

The device iommu probe/attach might have failed leaving dev->iommu to NULL and device drivers may still invoke these functions resulting in a crash in iommu vendor driver code. Hence make sure we check that. Also added iommu_ops to the "struct dev_iommu" and set it if the dev is successfully associated with an iommu.
